Sarana Tile lists Genesis Grey as a 10" x 11.6" porcelain mosaic. Residentially it works in kitchens, entry foyers and open-plan living areas. Commercially it is specified for retail floors, restaurant dining rooms and hotel lobbies. The nominal size is 10" x 11.6", listed metrically as 29.4x25.4cm. Each sheet covers roughly 0.8 sq ft. Sarana catalogues it in Volume 8 on page 100. It arrives mesh-mounted, so the spacing holds while the sheet is set and it trims down to meet a corner or a niche. Sarana prices it by the sheet.
